Cerbo GX tank sensor connections

This is a truly noob question. How do I insert the wires from the tank sensors into the plug? I assume I have to do something with the tiny orange levers on the plug but they don’t move easily and I don’t want to break one.

@kgiesselman just push the small orange piece in and the wire can be pushed further into the hole. When the orange tab is released the wire will be held firmly.

They are spring loaded and when released the internal spring holds the wire tight.

Thanks!
